Upper Limit Temperature Protection

MICROTEMP thermal cutoffs from Therm-O-Disc offer an accurate, reliable solution to the needfor upper limit temperature protection. Known as a thermal fuse, thermal link, or TCO, theMICROTEMP® thermal cutoff provides protection against overheating by interrupting an electricalcircuit when operating temperatures exceed the rated temperature of the cutoff.

Application

Major appliance

Portable appliance

HVAC

Water heater

Hair care Other

G4 Series

Rated for continuous operating currents up to 10 amps @ 250VAC (15 amps @ 120VAC), the G4series MICROTEMP TCO is the industry standard for over-temperature protection. The G4 series isapplied to millions of appliances and personal care products each year, providing reliable back-upprotection for temperature controlling thermostats and other over-temperature conditions. TheG4 series is also widely applied in office machines, portable heaters and industrial equipment as athermal safeguard.

MICROTEMP Features

• One-shot operation cuts off electrical power

• Current interrupt capacity up to 25 amps @ 250VAC

• Low resistance

• Compact size

Operating Principle of the MICROTEMP TCO

The active trigger mechanism of the thermal cutoff is an exclusively formulated, electricallynonconductive pellet. Under normal operating temperatures, the solid pellet holds spring-loadedcontacts closed.When a predetermined temperature is reached, the pellet melts, allowing the compression springto relax. The trip spring then slides the contact away from the lead and the circuit is opened (seefigures 1 and 2).After a MICROTEMP thermal cutoff opens a circuit, the TCO needs to be replaced. Thisreplacement procedure must include correction of the fault condition before the product isoperated again.

Emerson Electric (T-O-D) authorized dealers to supply the original original Emerson fuse (hot melting fuse), G4 series global universal fuse, G4A00240C/G4A01240C, rice cooker electric iron and other electrical fuse. If you need more understanding, welcome to inquire:

Special description: The MicroteMP hot melting fuse (temperature fuse) produced by the American Emerson brand "Therm-O-DISC" thermal disc company provides customers with a very accurate and reliable upper limit temperature protection. When the working temperature exceeds the rated temperature of the thermal fuse, it can quickly interrupt the circuit to avoid the harm caused by overheating. It has established its unshakable flagship status in the same industry products. The Emerson series temperature fuse has a small size that detects the function of abnormal temperature and cuts off the circuit, and a strong temperature overheated fuse. It detects the temperature of abnormal temperatures of household or industrial electrical products and quickly cut off the circuit in a timely manner to prevent the effect of preventing the damage. This series of temperature fuse is installed with thermist particles (organic chemicals) materials into the metal shell for excessive heat numbers. Its specialty can cut off a large current (rated current) of 5A to 25A

MicroTemp hot melting fracture has 5 basic models:

G4: [G4 series thermal fuse] The G4 series Microtemp® hot melting fuse made by the American Emerson brand "Therm-O-DISC" thermal disc company. According to different product specifications, the contact capacity can reach AC250V 10A and AC120V 15A, respectively With DC24V 5A, it can provide reliable overheating protection. Among the products in the same industry, the G4 series Microtemp hot melt fracture has established its unshakable flagship position. The G4 series thermal fuse is widely used in various instrumental appliances and personal electrical appliances every year, providing a very precise overheating protection, and providing reliable backup protection for internal temperature controllers. The G4 series thermal fuse, as the protector of the electrical appliances, is also widely used in various office equipment, portable electric heaters and industrial equipment.

G5: The G5 series Microtemp hot melting fracture is specially designed and applied to high -current loads. Depending on the product specifications, the contact capacity can reach AC250V 20A, AC277V 20A, and AC120V 25A, respectively. The G5 series thermal fuse is very similar to the G4 series thermal fuse, but the interior uses different structural design, which can disconnect the circuit in time in the face of higher current loads. The G5 series thermal fuse can provide reliable overheating protection, which are mainly used in various electric heater and other high -current load devices.

The G6 series Microtemp thermal fuse, which is small in size and can quickly disconnect the circuit to provide reliable overheating protection. The contact capacity can reach the AC250V 16A. Compared with the double metal sheet temperature controller, the price has a more competitive advantage.

The G7 series Microtemp thermal fuse is specially designed to design in product equipment that is used for high -current loads but pursuing minimal volume. The G7 series thermal fuse is only 1/3 of the G4 or G5 series, and the contact capacity is AC250V 5A and DC24V 5A. It is mainly used in various transformers, motors, battery packs and electronic circuits.

The G8 series Microtemp thermal fuse, small body shape, can quickly disconnect the circuit, provides reliable overheating protection, the contact capacity can reach AC250V 25A and 277V 20A. Compared with the single trigger device of the dual -metal sheet, it has more prices in terms of price. Competitive Advantage. With its small volume (the same as the G4 and G5 series thermal fuses) and the advantages of installation and thermal reaction, it is widely used in various equipment.

The E series is specially named for ROSH in the early days. The characteristics are the same as the G series
