Phoenix Contact 1019974 Circuit Breakers TMC 71C 03A

Product Description

The PHOENIX CONTACT 1019974 is a thermomagnetic circuit breaker designed for circuit protection. It provides protection against overcurrent up to a short-circuit current of 7.5 kA. The device increases reliability by isolating problems in the system while allowing for continued operation. It is suitable for AC and DC applications.

• Can be used worldwide due to international approvals
• Suitable for various grid types, as it is available in 1-, 2-, 3-pos. versions
• Ideally coordinated protection due to various tripping characteristics and a wide selection of nominal currents

Product Highlights

The TMC 7 series circuit breaker features snap-action technology and a trip-free design, increasing product longevity and ensuring safety.
