Why Choose the ABB OTP45BA3M 3-Pole IP65 Enclosed Switch Disconnector?
The ABB OTP45BA3M is a robust 3-pole plastic enclosed switch disconnector designed for local electrical isolation and load switching in industrial machinery, motor control systems and low-voltage electrical installations. Part of the ABB OTP enclosed switch range, it combines reliable manual operation with a durable protective enclosure and a clearly identifiable red and yellow operating handle.
Featuring an IP65-rated, glass-fibre-reinforced polycarbonate enclosure, the OTP45BA3M provides protection against dust and low-pressure water jets. Its red and yellow selector handle can be padlocked in the OFF position, supporting safe maintenance procedures and helping prevent unintended operation of connected equipment.
The OTP45BA3M is identified by ABB order code OTP45BA3M and manufacturer product ID 1SCA022401R3600. ABB's published product data specifies a 45 A AC-23 operational current rating and 22 kW switching capability at 415 V AC, while the supplied product description identifies a 15 kW application. The final suitability of the switch must be assessed against the connected load, operating voltage and applicable utilisation category.

Reliable Local Isolation for Industrial Motors and Electrical Equipment
Enclosed switch disconnectors such as the ABB OTP45BA3M provide a local means of disconnecting machinery and electrical equipment from their power supply. The manually operated rotary mechanism opens or closes the main switching contacts, enabling operators and maintenance personnel to isolate equipment before inspection, servicing or repair.
The three-pole construction enables simultaneous switching of three phase conductors, making the OTP45BA3M suitable for compatible three-phase installations. The fixed neutral terminal provides a connection point for a neutral conductor without introducing a fourth switched pole. Its padlockable red and yellow handle supports controlled isolation procedures, while the interlocked cover helps restrict access to internal components during normal operation.
The IP65 polycarbonate enclosure provides protection in industrial environments where dust, moisture and mechanical exposure must be considered. For motor applications, the switch should be selected according to the motor's full-load current, starting characteristics, operational voltage and applicable utilisation category. Appropriate upstream overcurrent and short-circuit protection must also be provided.
