Product Introduction
ZYMM1-400M covers rated current of 200A, 225A, 250A, 315A, 350A and 400A, rated insulation voltage of 800V, rated impulse withstand voltage of 800V, rated working voltage of AV 400V and 690V. The MCCB can detect a short circuit when it occurs and automatically switches off when detected by a sensing element or relay contact, without the need to press any button on the panel.
Yuming moulded case circuit breaker is designed to use in small distribution networks at 50 Hz or 60 Hz AC and has a rated operating voltage of 690 V. It protects circuits and power supply equipment from overload, short circuit and undervoltage faults.

FAQ
Q:Is the MCCB suitable for DC applications?
A:Yes, MCCBs with thermal-magnetic release are suitable for DC applications. The thermal rating of these MCCBs remains the same. However, MCCB's based on static or microprocessor release are not suitable for DC applications.
Q:What’s the difference between MCCB and fuse?
A:The MCCB is an alternative to fuses as it does not need to be replaced once an overload has been detected.
