Product Description
Benshaw RSC-22-6AC120 RediStart Contactor — 22A, 3-Pole, 120V AC Coil
The Benshaw RSC-22-6AC120 is a 22A, 3-pole IEC contactor from the Benshaw RediStart RSC series, rated for 7.5 HP at 230V and 10 HP at 460V three-phase. It comes factory-installed with one side-mounted auxiliary contact block (1 NO / 1 NC), screw terminals, and mounts on standard 35mm DIN rail. The coil operates on 120V AC. For complete motor overload protection, the Benshaw SPO-22 series thermal overload relay mounts directly to the RSC-22 contactor frame.
Note: The RSC series has been superseded by the Benshaw RC series. The current equivalent replacement is the RC-22A-56AC120, which shares the same 22A rating, 3-pole configuration, 120V AC coil, and DIN rail footprint. Note that the RC-22A carries updated HP ratings (10 HP @ 230V / 15 HP @ 460V) reflecting current IEC motor standards. Kent Electrical Supply stocks both RSC and RC series units — contact us at 1-800-222-5129 to confirm availability and interchangeability for your application.

Product Features
- One Auxiliary Contact Block Included: The RSC-22-6AC120 ships with one factory-installed side-mounted auxiliary contact block containing 1 NO and 1 NC contact. Additional top-mounted auxiliary blocks can be added for more signalling circuits.
- IEC-Rated Construction: Built to IEC standards for resistive and inductive loads up to 660V AC. Rated for AC-3 motor starting and running duty at up to 10 HP at 460V three-phase.
- 35mm DIN Rail Mounting: Snaps directly onto standard 35mm DIN rail. Screw terminals accept standard control wiring for fast panel installation.
- Compatible with SPO-22 Overload Relay: For complete motor overload protection, the Benshaw SPO-22 series thermal overload relay mounts directly to the RSC-22 contactor frame, creating a complete IEC motor starter assembly with protection against overloads, phase failure, long starting times, and motor stalling.
- RSC Series Superseded by RC Series: The RSC-22-6AC120 has been replaced in current production by the RC-22A-56AC120. The RC-22A offers the same frame size, coil voltage, and 1 NO/1 NC auxiliary contact, with updated HP ratings reflecting current IEC motor standards.
- 2-Year Benshaw Warranty: Every Benshaw RediStart contactor carries a full two-year warranty — twice the standard one-year warranty offered by most competing brands. Benshaw calls this the Benshaw Promise.

Frequently Asked Questions
Is the RSC-22-6AC120 still available, or has it been discontinued?
The Benshaw RSC series has been superseded by the newer RC series. The RSC-22-6AC120 may still be available as new-old-stock while supply lasts. The current production equivalent is the RC-22A-56AC120, which is a direct drop-in replacement with the same 22A rating, 3-pole configuration, 120V AC coil, and 1 NO/1 NC auxiliary contact. Contact Kent Electrical Supply at 1-800-222-5129 to confirm current stock status of both units.
What is the difference between the RSC-22-6AC120 and the RC-22A-56AC120?
Both are 22A, 3-pole Benshaw RediStart contactors with 120V AC coils and the same DIN rail footprint. The key difference is the HP rating: the RSC-22 is rated at 7.5 HP @ 230V / 10 HP @ 460V, while the RC-22A carries updated ratings of 10 HP @ 230V / 15 HP @ 460V. Both include 1 side-mounted auxiliary contact block (1 NO / 1 NC) and carry the 2-year Benshaw Promise warranty. For new installations, the RC-22A-56AC120 is the preferred choice. For like-for-like replacement of an existing RSC-22, either unit will work mechanically and electrically.
Which overload relay is compatible with the RSC-22-6AC120?
The Benshaw SPO-22 series thermal overload relay is designed to mount directly to the RSC-22 contactor frame, creating a complete IEC motor starter assembly. The SPO-22 provides bimetallic overload protection against overloads, phase failure, long starting times, and motor stalling. If you are building a new starter around the current RC-22A contactor instead, use the RMSO series overload relay, which is designed for the RC frame. Call us at 1-800-222-5129 for help selecting the correct overload range for your motor’s full-load amperage.
What does “6AC120” mean in the RSC-22-6AC120 part number?
In Benshaw RSC series part numbers, the suffix encodes the coil voltage. “6AC120” indicates a 120V AC, 60 Hz coil. Other common coil voltages in the RSC-22 family include 24V AC (6AC24), 208–240V AC (6AC240), and 480V AC (6AC480). Always verify your control circuit voltage before ordering to ensure the coil voltage matches your panel design.
Where does the RSC-22 fit in the Benshaw RSC contactor family?
The RSC-22 sits between the RSC-12 (12A, 7.5 HP @ 460V) and the RSC-32 (32A, 20 HP @ 460V) in the Benshaw RSC series lineup. It is the right choice when your motor falls in the 10 HP range at 460V and you need the compact footprint of the smaller RSC frame with only one auxiliary contact set. For higher horsepower applications requiring two sets of auxiliary contacts (2 NO / 2 NC), the RSC-32-6AC120 is the next size up.
Does the RSC-22-6AC120 qualify for same-day shipping?
Yes — when in stock, the RSC-22-6AC120 ships same business day from Kent Electrical Supply’s warehouse in Emmaus, PA when ordered before 4:00 PM EST. Current stock quantity is shown on this page. For bulk orders or questions about availability, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
