Power circuit breaker 3p 250A 50kA ВА-303Rc Sel 100/300/500mA 0.4/0.5/1s DEKraft 28549DEK

VA-300Rc series molded case circuit breakers are designed for use in AC power distribution circuits. These devices are used in networks with a voltage of up to 400/415 V and 50Hz for electrical energy distribution, as well as for protecting circuits and equipment from damage caused by overloads and short-circuit currents, for protecting people from electric shock, and for fire protection. VA-300Rc series circuit breakers are equipped with a non-adjustable thermomagnetic trip unit, which allows adjusting the current and trip time via differential protection when selecting devices with selective protection.
