30 A continuous rating and 4-pole configuration
The A16-04-00-84: Rated 30 A continuous at 600 VAC, this 4-pole contactor handles three-phase motor loads plus a neutral pole or a second independent load circuit in the same package. The 120 VAC coil matches standard control transformer secondaries found in North American panels — no separate DC supply or dropping resistor needed.
Normally-closed contact logic for fail-safe circuits
All four contacts are N.C. (normally-closed), meaning the load circuit is closed when the coil is de-energized — this suits safety interlocks or fail-safe holding circuits where loss of control power must keep the load connected. In a standard motor starter the N.C. configuration is unusual; verify the BOM logic before substituting into a circuit designed around N.O. contacts.
