BS 842 is a British Standard which specifies the requirements for a.c. voltage-operated earth-leakage circuit-breakers having rated voltages not exceeding 500 volts and rated currents not exceeding 200 amperes.
BS 842 specifies the definitions, service conditions and rating with respect to a.c. voltage-operated earth-leakage circuit breakers.
BS 842 on earth-leakage circuit breakers is helpful for:
Having access to reliable guidelines is essential to prepare and use quality earth-leakage circuit breakers. BS 842 provides manufacturers with the standard arrangements, terminal identification requirements, construction methods, and operating mechanism along with the test requirements and test certificate.
BS 842 allows manufacturers to effectively produce and test earth-leakage circuit breakers. BS 842 provides users with efficient and standardized earth-leakage circuit breakers.
