Circuit breakers

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current, typically resulting from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.

Control products

DCS products, solutions, services for continuous or batch process industries, infrastructure, energy and utilities – delivered in collaborative control rooms.

Enclosures and cable systems

The move to higher density servers and switch applications has increased the cable quantity for both data and power. In addition, higher speed data cables are becoming larger in diameter. These factors are pushing the usable space within the enclosure to the limits. These factors all contribute to the increased emphasis on cable management, especially when poor cable management can lead to system failures.
