Description
The Circuit Breaker NZMS3-4-VE630 is a high - breaking electronic protection molded case circuit breaker. It has the following features:
- High Breaking Capacity：It can provide electrical protection for low - voltage power distribution systems and equipment with a rated current up to 630A，and its breaking capacity is 50kA，ensuring reliable protection in case of short - circuit faults.
- Electronic Trip Unit：The electronic trip unit allows for precise and adjustable protection settings. It can measure the r.m.s. value and has a “thermal memory” function，which helps to overcome current peaks and provides accurate protection against overloads and short - circuits.
- Adjustable Time Delay：The trip unit also has an adjustable time delay setting. It can be set to tr at 6x Ir and even to infinity (without overload releases)，which is useful for avoiding nuisance tripping due to temporary current surges，ensuring stable power supply in various operating conditions.
- Wide Application：It is suitable for a wide range of applications，including systems，cable，selectivity and generator protection，making it a versatile choice for different electrical systems.
