SIEMENS 40BP32AG 277VAC 3P Contactor
The SIEMENS 40BP32AG is a NEMA size 0 non-reversing magnetic contactor rated for 9 amps inductive load at 277 VAC. It suits industrial control panels that switch three-phase motor circuits or resistive heating elements. The unit includes one normally open auxiliary contact and accepts up to eight auxiliary modules for expanded control logic. Surface mounting and screw terminals simplify panel integration.
Verify coil voltage and enclosure needs
Confirm the control circuit operates within the 190-220 or 220-240 VAC coil range before ordering. The contactor ships with no enclosure, so the panel must provide the required environmental protection. Ensure the three-pole configuration matches the load wiring plan and that the 9 amp inductive rating covers the intended motor full-load current. Auxiliary contact capacity should align with the control scheme.
Surface mount with screw terminals
The contactor measures 4.31 inches high by 4.25 inches wide, fitting standard panel layouts. Screw terminals accept ring or fork lugs for secure power and control connections. Surface mounting uses through-holes for direct attachment to the sub-panel. The open design allows visual inspection of contact wear and easy terminal access during maintenance. Series 40 construction follows NEMA standards for industrial durability.

Questions about this item
Does the Siemens 40BP32AG contactor include mounting hardware or auxiliary contact blocks, or must they be purchased separately?
The contactor is supplied as a single unit with screw terminals for wiring. Mounting hardware and additional auxiliary contact blocks up to the module capacity of 8 are sold separately.
Which coil voltage version should I select for a 277 VAC control circuit?
This model operates on a 190-220/220-240 VAC coil; a 277 VAC coil is not available for this NEMA Size 0 contactor.
What does the 9 A inductive current rating mean when the contactor is installed in a motor circuit?
It indicates the maximum full-load inductive current the three main poles can switch at the rated coil voltage, suitable for motors up to that ampacity.
