Will trip open on overload, even when the handle is forcibly held on or restrained. This prevents operator from damaging the circuit by holding the handle in the ON position.
The operating handle moves positively to the OFF position on overload.
Operates normally in temperatures between –40°C and +85°C.
Not less than 100 megohms at 500Vdc.
Withstands 1500Vac at 60Hz for 60 seconds or 1800Vac for one second from terminal to terminal, and from auxiliary switch terminal to main terminal.
Per UL 1077 (6000 operations at rated load plus 4000 operations with no load). Tested at a maximum rate of 6 times per minute. Rating above 50 amperes operate a minimum of 5000 operations.
Withstands 100G or more without tripping while carrying full rated current per MIL-Std-202, Method 213, Test Condition I. Instantaneous types (delay 40, 50, 60 and 49, 59, 69) and dual coil configurations are tested at 80% of rated current. Protectors mounted in the handle down position are to be tested with no current applied (per MIL-PRF-55629).
Withstands 10G without tripping while carrying full rated current per MIL-Std-202, Method 204, Test Condition A. Instantaneous types (delay 40, 50, 60 and 49, 59, 69) and dual coil configurations are tested at 80% of rated current.
Dual Coil Ratings
5-65Vdc and 5-250Vac for three terminal configurations. 5-120Vac and 5-120Vdc for four terminal configurations. Not available in delays 64, 65 and 66.
0.050-50 amperes, 65Vdc, 250Vac maximum, 50/60Hz or 400Hz. 51-100 amperes at 65Vdc and 120Vac maximum. Ratings of 0.050-20 amperes at 277Vac, 50/60Hz are available upon request.
