Description

The CE 400A Load Break Switch Lbs 3 Phase is engineered for reliable circuit isolation and control in electrical systems. Designed for operations at AC 50Hz, it supports a rated voltage of up to 660V and DC voltage of up to 440V. With a robust rated current capacity of up to 3150A, this switch is ideal for infrequent circuit making and breaking. It features an innovative elastic-accumulating accelerating mechanism that ensures rapid operation at 13.8m/s, independent of the handle speed, significantly enhancing arc-extinguishing capabilities.

Constructed from unsaturated polyester resin reinforced with glass fiber, the switch exhibits exceptional flame resistance and dielectric performance, ensuring safe operation. The parallel double gap contacts are self-cleaning, enhancing durability and functionality. All contacts are made from copper alloy plated with silver, providing two separation contact surfaces and ensuring a large insulation clearance. Additionally, the handle can be locked in the “0” position with three locks simultaneously, preventing erroneous operations.
