Notes: DCR and impedance based on 100% rated current applied and stablized a minimum of one hour.

Tolerance: .02 amperes to 2.5 amperes, ± 20%; 2.6 amperes to 20 amperes, ± 25%; 21 amperes to 50 amperes, ± 50%. Consult factory for special values and for coil

Notes:

DC units do not require series fusing.

277Vac: A circuit protector with this voltage rating is intended for 277Vac per pole single phase source only usage. (e.g.) If a two or three pole breaker is marked

277Vac, all line terminals must be connected to the same phase, assuming the 277Vac is taken from line to neutral of a three phase 277/480Vac system.
