NEMA Size 2 Contactor for Motor Control
This SIEMENS 40FP32AD is a non-reversing magnetic contactor rated for 45 A inductive loads at 208 VAC. It suits industrial panels and machine shops that need reliable three-pole switching for motors and resistive heating circuits. The open-frame design mounts directly on a surface without an enclosure.
208 VAC Coil Voltage Determines Compatibility
The contactor operates from a 208 VAC control circuit, so the panel’s control transformer or supply must match this exact voltage. A different coil voltage will prevent the contactor from pulling in or cause overheating, making this the single specification that decides whether the part fits the application.
Screw Terminals Handle Continuous 45 A Loads
Under sustained operation the three main poles carry the full 45 A inductive rating through screw terminals sized for secure, low-resistance connections. The NEMA Size 2 frame dissipates heat without forced cooling, and the single 1NO auxiliary contact remains available for status feedback throughout the duty cycle.

Questions about this item
What does the 45 A inductive rating mean for the loads I can switch?
The contactor is rated to switch three-phase inductive loads up to 45 A at 208 V AC per pole.
How does the 208 V AC coil voltage limit the control circuit?
The coil requires a 208 V AC control signal; a different control voltage will not energise the contactor.
What clearance is needed to surface-mount the 4.88 in by 4.25 in body?
Allow at least 4.88 in height and 4.25 in width on the mounting surface for the contactor footprint.
