DZ47LE-125 Small Leakage Circuit Breaker
Short Description:
DZ47LE-125 is applicable to a line of AC 50Hz/60Hz, rated voltage 230V forsingle pole two-wire, 2-pole or 400V for 3-pole, 3-pole 4-wire, 4-pole andrated current up to 40A. It can protectthe line and motor from overload andshort circuit. It can also be used for infrequent line conver-sion andinfrequent motor start. It conforms with the standards of IEC60947-2.
