Moulded Case Circuit Breaker MCCB Adjustable 4P Battery Protection Switch Isolator 250A UCB 250H

Feature: 1. GOOD ELECTRICAL CONDUCTIVITY: The contacts are made of copper and nickel plated, which has good electrical conductivity and is safe and reliable 2. GOOD FLAME RETARDANCY: The thermosetting material has good flame retardancy, will only gradually carbonize even if encounters an open flame, and will not burn, which is safe 3. SHORT CIRCUIT AND OVERLOAD PROTECTION: Come with the characteristics of small size, short circuit protection, overload protection, flame retardant shell, high segmentation, short arcing, etc. 4. PROTECT CIRCUITS AND POWER EQUIPMENT: Mainly used to distribute electric energy and protect circuits and power equipment from overload, short circuit, under voltage and other faults, also be used for infrequent starting and overload, short circuit and under voltage protection of the motor 5. ‑20℃‑60℃ ENVIRONMENTAL OPERATING TEMPERATURE: Rated current for 250A, frequency is 50/60Hz. Environmental operating temperature from ‑20℃‑60℃, suitable for more extreme environments Specification: Item Type: Moulded Case Circuit Breaker Model: UCB 250H Material: Bulk molding compound thermosetting plastic + contact copper Rated Current: 250A Frequency: 50/60Hz Rated Insulation Voltage (Ui): AC 690V Rated Voltage (Ue): AC 660V Rated Impulse Withstand Voltage (Uimp): 6KV Ics=50%Icu Rated Voltage (Ue) AC 600v/660V AC 480/500V AC 440/460V AC 380V/415 AC 220/240V DC 250V DC 125V Rated limit breaking current (Icu) 20KA 30KA 42KA 42KA 85KA 25KA 40KA Package List: 1 x Circuit Breaker 3 x Partition Board 1 x Screw Pack
