Procurement Intelligence
The OTR45BA3M is ABB's OTR series 3-pole switch disconnector, a load-break isolator for manual circuit disconnection in industrial/commercial switchboards with IP65 enclosure protection. Critical verification: confirm 63A rating matches downstream protective device coordination and verify screw terminal torque specifications (typically 2.5 Nm) to prevent contact degradation.
