TeSys Deca Contact Switching and Motor Control Characteristics

The LC1D32M7 uses a three-pole contact arrangement for AC motor switching applications. The power circuit supports AC-3, AC-3e, AC-1 and AC-4 utilization categories. The device includes one normally open and one normally closed mechanically linked auxiliary contact, with the NC contact certified as a mirror contact according to IEC 60947-4-1.

The contactor operates with a standard AC control circuit without an integrated suppressor module. Coil operating limits are defined by the control voltage range, with closing operation between 0.8 and 1.1 Uc at 50 Hz and 0.85 to 1.1 Uc at 60 Hz within the specified temperature range.

Frequently Asked Questions

Q: Does the LC1D32M7 support hot-swap replacement during operation?
A: No. The contactor is a mechanical switching device and requires power isolation before removal, wiring changes, or replacement.

Q: What type of terminal connection is used for the LC1D32M7?
A: The contactor uses screw clamp terminals for both power circuit and auxiliary circuit connections.

Q: What auxiliary contacts are integrated into the device?
A: The standard configuration includes 1 NO and 1 NC mechanically linked auxiliary contacts, with the NC contact providing mirror contact functionality.

Field Installation Guidelines

Install the contactor on a suitable mounting plate or DIN rail with sufficient clearance for conductor routing and terminal access.

Power and control wiring should be routed separately where required by cabinet design practices. Verify terminal tightening torque according to the specified values: control terminals 1.7 N.m and power terminals 2.5 N.m.

Confirm that the installation environment remains within the specified operating temperature range and apply derating when ambient temperature exceeds 60 deg C.

Maintain protective conductor routing, correct phase identification, and proper enclosure grounding according to the applicable electrical installation standard.
