Siemens 45 A 3-Pole Contactor

The Siemens 40FP32AF is a non-reversing magnetic contactor rated for 45 A inductive load at 110/120 V AC. It uses a NEMA Size 2 frame with three power poles and one normally open auxiliary contact. Surface mounting and screw terminals simplify installation in industrial control panels.

Coil Voltage and Enclosure Limits

The 110/120 V AC coil voltage restricts use to control circuits operating at that specific level. The unit ships with no enclosure, so the installer must provide a suitable NEMA-rated housing for the environment. Auxiliary contact capacity allows up to eight additional modules for expanded control logic.

45 A Inductive Current Rating

The decisive specification is the 45 A full-load inductive current rating at NEMA Size 2. Select this contactor only when the motor or load matches that current demand and a non-reversing three-pole configuration is required. Builders needing reversing operation or a different current rating must choose another device.

Questions about this item

Should I pick the 45 A inductive version or a resistive-rated alternative?

This contactor is rated 45 A for inductive loads and has no resistive rating, so choose it for motor or transformer switching rather than pure heating circuits.

What does the 45 A inductive rating mean once the contactor is installed in a panel?

It can continuously carry 45 A on each of its three poles when switching inductive loads such as motors, provided the coil receives 110/120 V AC and the enclosure is ventilated.

How does the 110/120 V AC coil voltage limit what controllers can drive it?

The coil only operates on 110/120 V AC, so a PLC or relay output must supply that exact AC voltage; low-voltage DC signals cannot drive it directly.
