FAQs
The BAB2045S uses bolt‑on mounting and is designed for straightforward retrofit into standard industrial panels. Its compact footprint (3.9 in L × 4.8 in H × 2.2 in W) and 1 lb weight ease installation in tight spaces, while maintaining secure, vibration‑resistant mounting suitable for automation enclosures and control cabinets.
It is a two‑pole device rated at 45 A with a 10 kAIC interrupt capacity at 240 V. The unit operates on 120/240 V and features a non‑interchangeable trip type, Quicklag thermal‑magnetic action, and a 1‑year warranty, ensuring predictable protection for motor loads and control circuits.
Yes. The HACR rating confirms suitability for HVAC equipment, and the 45 A/10 kAIC rating supports motor‑control applications. Its UL Listed and CSA Certified status further ensures compliance in HVAC and general automation panels, making it a reliable choice for climate control and fan/compressor circuits.
The shunt trip (120–240 V) enables remote trip initiation, allowing safety interlocks and emergency shutdowns to isolate circuits quickly. This is critical in production lines where rapid power isolation protects personnel and equipment during faults or maintenance.
With a standard 1‑year warranty and robust thermal‑magnetic design, expect low maintenance while ensuring periodic visual inspections and contact resistance checks in high‑duty environments. The device’s durable construction and listed certifications reduce procurement risk and support long‑term reliability in automated systems.
