Description
Built for heavy-duty industrial environments, this 40A, 3-pole current-limiting MCCB provides reliable thermal-magnetic protection. It includes a built-in 120VAC shunt trip, allowing for remote circuit interruption when required. This breaker mounts into Square D I-Line panelboards. If a modern equivalent is needed, it can be replaced by the HRA36040 along with the S29386 shunt trip accessory. With a massive 200 kAIC interrupt rating at 480VAC, it restricts peak fault currents effectively.
