Description
Designed for advanced control, this 70-amp miniature breaker includes a built-in shunt trip mechanism for remote power shutoff in commercial settings. The device bolts firmly into Eaton and legacy Westinghouse Pow-R-Line panelboards. Its fixed thermal-magnetic trip unit ensures consistent overcurrent response. Capable of interrupting 22kA at 120/240VAC, it provides superior fault clearance. The non-interchangeable trip design maintains strict calibration standards.Specifications

Product FAQs
7 answersWhich panelboards are compatible with the Eaton QBHW2070S circuit breaker?
This bolt-on breaker is designed for use in Eaton Pow-R-Line panelboards and legacy Westinghouse panelboards that accept Quicklag BAB or QBHW frame types.
Does the QBHW2070S include a shunt trip, and how does it affect panel space?
Yes, the "S" suffix indicates a factory-installed shunt trip for remote disconnect capabilities. The shunt trip mechanism requires one additional pole space on the right side of the breaker, meaning this 2-pole breaker will occupy three spaces in your panelboard.
What is the operating voltage and current draw for the shunt trip on this breaker?
The standard "S" suffix shunt trip operates at 120VAC and draws 2.6A during activation.
What wire sizes are compatible with the terminals on the QBHW2070S?
The box lugs on this 70A breaker are rated to accept wire gauges ranging from 8 AWG up to 1/0 AWG.
What is the difference between the QBHW2070 and the QBHW2070S?
Both are 70A, 2-pole, 22kAIC bolt-on breakers. The QBHW2070S includes a factory-installed shunt trip for remote tripping, whereas the standard QBHW2070 does not.
What type of trip unit is installed in the QBHW2070S?
It features a fixed thermal-magnetic trip unit that provides both long-time protection against overloads and instantaneous protection against short circuits.
How does this breaker connect to the panelboard?
The QBHW2070S utilizes a bolt-on connection, providing a secure, vibration-resistant mechanical and electrical attachment directly to the panelboard bus.
