- PSL air circuit breaker series (referred to as circuit breaker in the following) can be applied to 50Hz/60Hz power grid, rated current 800A~4000A, rated insulation voltage 1000V, rated operating voltage up to AC440V. It can protect circuits and devices from overload, short circuit, low voltage, grounding fault and the harmful effects of other faults. It can also be supplied as the isolating switch is non-automatic (no travel parts). It can provide selective protection with high precision and also improve the safety and reliability of power supply.
- Trip units come in a full range of types and flexible
- Various types of travel units are optional: PVR21 – Basic functionality Digital LED display and simplicity of use. PVR21V with voltage measurement built-in functions; PVR22 – more advanced functionality with LCD display, optional voltage (PVR22V) and power meter.
- Current protection features: A wide range of protection functions are provided including long time overload protection, short time delay, instantaneous fault, earth fault, neutral current N pole protection, current unbalance protection, MCR circuit breaker capacity protection;
- Optional remote reset function for remote recovery after error
- Long electrical life and short circuit tolerance The circuit breaker design uses high strength DMC material, which has good electrical insulation and mechanical strength. Double contact structure improves the electrical life of the product; The optimized design of the mechanism realizes contact pressure compensation, and improves product reliability and short-circuit tolerance.
- More safety protection features
- It has drawer-type circuit-breaker door interlocks, drawer-type three-position interlocking and key-locking devices, rear terminal protection cover, ready-to-close indicator and devices other protection.
