Designed specifically for world market applications, the B-series
utilizes the hydraulic magnetic principle which provides precise
operation and performance even when exposed to extremely
hot and/or cold application environments.
Typical applications include power supplies, medical equipment,
office equipment, control panels and marine equipment. In addi-
tion, these breakes meet CSA Standard 22.2 No. 100 for the
Generator & Welder markets.
1-6 poles, 0.02 - 50 amps, up to 277 VAC or 80 VDC, with
choice of time delays, terminals and actuator colors.
