Product Details

Mcb electrical miniature mini circuit breakers 1P 2P 3P 4P types Mini Circuit Breakers

Application Scope

- The ERB1-125 series miniature circuit breakers is suitable for
circuits with AC 50/60HZ,a rated voltage of 400V or a single-phase
voltage of 230V,and a rated current of 100A and below.It is used
for short circuit and overload protection for buildings and
electrical equipment ,and can also used for infrequent line
switching under normal circumstances.It can also be used as a
disconnecting switch and for under -voltage protection and remote
breaking for circuits .
 
The product features good -looking appearance ,small size ,light
weight ,accurate current tripping and setting .Reliable operation
,high breaking capacity ,fast tripping ,rail mounting ,combined
mode design .Combined with auxiliary contact ,alarm indication
contact ,under -voltage trip unit ,shunt trip unit and other
accessories ,it would meet the needs from various users .Its case
and components adopt high flame -retardant and impact -resistant
plastic materials ,featuring a long service life.
 
- Standards complied by this product: IEC60947-2, GB14048.2.

Main Technical Parameters

- Main type - The rated currents of the circuit breaker are 63A,
80A, 100A, 125A - The number of poles of the circuit breaker is
divided as: unipole, two-pole, three-pole and four-pole. - The
circuit breaker is fitted with a 35x7.5 standard mounting rail.

The rated values of the main circuit of the circuit breaker are
shown in Table 1.

Table 1
Rated current(A)	Number of poles	Rated voltage(V)	Rated short circuit breaking capacity
			Expected current in the last test line(A)	Power factor
63,80,100,125	1,2,3,4	230/400	4000	0.45~0.50

The characteristics of over-current trip are shown in Table 2.

Table 2
Ambient air humidity	I/In	Expected result in the last test		Start status
		In≤63A	In>63A
30±2°C	1.05	Not trip within 1 hour	Not trip within 2 hours	Cold status starts
	1.30	Not trip within 1 hour	Trip within 2 hours	Hot status starts
	3.0	Release time>3s	Release time>5s	Hot status starts
-5～45°C	5.0~10.0(C)	Operate within≤0.1s		Cold status starts
	10.0~14.0(D)	Operate within≤0.1s

Ower frequency withstand voltage :After testing the resistance to
heat and humidity, the circuit breaker should withstand a 2500V
power frequency withstand test for 1 minute without arc-over or
breakdown .
 
Mechanical and electrical life: the mechanical life of the circuit
breaker is 4000times, in which the electrical life is 1500times .
