product details
scope of application
ZHHB1-63/125circuit breaker with shunt release (hereinafter referred to as circuit breaker), with intelligent shunt trip function, suitable for ac 50 Hz(or 60 Hz),rated operating voltage is 230 /400V, in lines with a rated current of up to 125, the line can be remotely controlled or automatically signal-controlled to break, and at the same time it can protect the line from overload and short circuit, and can also be used for infrequent line replacement. currently, it is widely used in C the card prepaid electricity meter is used to control the on and off of the line.
circuit breaker complies with 1 EC60898-1、GB10963.1 standard.
model and meaning
features
this circuit breaker is made of ZHHB1 it is assembled from a small circuit breaker and an intelligent module shunt release. the inner parts are positioned by the material shell. the shell is made of flame-retardant arc-resistant high-strength new material, so it has good impact strength and flame-retardant properties. the contact system adopts an electric repulsion mechanism, which greatly improves the breaking capacity of the circuit breaker. the intelligent module transfer tripper can protect the tripping coil from being burned and strong electromagnetic interference generated by the induction cooker at low voltage and still work normally.
this product is designed for single-phase, three-phase four-wire C designed for use with card energy meters, it has inverse time overload protection and short circuit protection functions and can receive C the signal of the card energy meter cuts off the circuit to prevent users from defaulting on electricity bills. it has high interruption, small size and reliable performance.
