What does normally closed mean on the EE Controls LSN7-04-C?

Normally closed means the contactor keeps the lighting circuit on when the coil is not energized. The coil must be continuously powered to switch lights off.

What is the coil voltage on the LSN7-04-C?

The LSN7-04-C uses a 208/230 VAC 50/60 Hz control coil. 208/230VAC suits applications on 208V or 230V single-phase systems, common in smaller commercial buildings and some international installations.

When should I use the LSN7-04-C?

Use the LSN7-04-C when your application requires a fail-safe lights-on condition, such as occupied commercial spaces, egress lighting zones, or systems where lights should stay on during a control circuit failure.

What loads is the LSN7-04-C rated for?

The LSN7-04-C is rated for ballast and LED lighting loads at 30A up to 600VAC. It is suitable for fluorescent ballast, HID ballast, and LED driver loads.

What happens to the lights if the control circuit fails on the LSN7-04-C?

The LSN7-04-C is normally closed, so if the control circuit loses power or fails, lights remain on. This makes it the correct choice for occupied buildings, egress zones, and any application where lights-off on control failure is unacceptable.

Are other coil voltages available in the same 4-pole Normally Closed series?

Yes. The same 4-pole Normally Closed configuration is also available with 24VAC (LSN7-04-G), 277VAC (LSN7-04-H), 347/380VAC (LSN7-04-D), and 208/230VAC (LSN7-04-C) coil voltages. Links to all variants are on this page.

What standards does the LSN7-04-C comply with?

The LSN7-04-C is listed to UL 508, CSA 22.2 #14, and IEC 60947. It also carries CE and RoHS approvals, making it suitable for use in the USA, Canada, and internationally.
