LS Electric Contactor MC-9a MC-12a Coil Voltage 24VDC 120VDC 240VDC (MC9A-30-10-B7-S-E) (MC-12a AC120V 50/60Hz)

Description

A 3-pole magnetic contactor rated around 9 A in the MC-9a frame, with one NO auxiliary contact, screw-terminal connections and an AC24 V 50/60 Hz coil version for DIN-rail / panel assembly.

LS Electric Contactor MC-9a MC-12a Coil Voltage 24VDC 120VDC 240VDC (MC9A-30-10-B7-S-E) (MC-12a AC120V 50/60Hz)

This is the compact utility contactor in the Metasol line – small footprint, DIN-rail or panel mounting, suitable for light motor or control loads. Its AC24 V coil makes it convenient for low-voltage control logic environments. Good choice when you don’t need high current capacity but want LS’s build quality. Trade-off: limited to lower currents/responsibilities compared to larger frames.

Pros

• Compact size (fits panel-dense layouts)
• AC24 V coil variant makes integration into low-voltage control circuits easier.
• DIN-rail or panel screw-mount capable — flexible installation.

Limitations

1. Rated current is modest (~9 A) – unsuitable for larger motors without upsizing.
2.  Auxiliary contact count is limited (1 NO) in this variant – may not suffice for complex control schemes.

Typical use cases

• Starting/control of small three-phase motors (e.g., small fans, pumps) where the current draw is modest.
• Switching control loads or relays in machine control panels with 24 V control logic.
• OEM equipment or panel installations where space is tight and a compact contactor suffices.
