EE Controls LSN7-04-D : 4-Pole Lighting Contactor, Normally Closed, 347/380 VAC 50/60 Hz Coil Voltage, 30A Maximum Amperage Rating Ballast / LED , IEC 60947 / UL 508 / CSA 22.2 #14 Standards
The EE Controls LSN7-04-D is a 4-pole, normally closed, electrically held lighting contactor rated for 30A ballast and LED loads at up to 600VAC, with a 347/380VAC control coil. Designed for lighting control panels and energy management systems, a single 347/380VAC control signal switches up to four lighting circuits simultaneously.
Best for: Best for commercial lighting control applications that require a fail-safe lights-on default with a 347/380VAC control coil.
Why Normally Closed — and Why It Matters for Your Application
A normally closed (NC) lighting contactor keeps lights on by default and requires a continuously energized coil to turn them off. In a fail-safe lighting design — common in occupied commercial and institutional buildings — the NC configuration ensures lights remain on if the control circuit loses power or fails. This eliminates the need for more expensive latching contactors in applications where lights-on is the required fail state. If your specification or sequence of operations calls for fail-safe illumination, this is the correct choice.

Normally Closed (NC)
Lights are ON when coil is de-energized. Coil must be continuously energized to keep lights OFF. Use when fail-safe lighting is required — lights stay on during any power or control failure. Common in occupied commercial buildings, egress lighting zones, and circuits where lights-on is the required default state.
Normally Open (NO)
Lights are OFF when coil is de-energized. Coil must be continuously energized to keep lights ON. Use when energy savings is the primary goal and lights-off on control failure is acceptable. Common in unoccupied zones, after-hours scheduling, and demand response applications.
