Part of ABB's OTM series, this unit combines a motor-drive actuator module with a 4-pole load break switch rated at 415V\/250A in AC-31B and AC-33B duty, making it suitable for both resistive and motor load changeover applications. With an impulse withstand voltage (Uimp) of 12kV, a short-time withstand current (Icw) of 15kA for 100ms, and a making capacity (Icm) of 30kA, the OTM250E4CM230C meets the most demanding fault-level requirements in industrial and commercial power distribution environments. Also rated under IEC 60947-3 at 690V\/250A AC-23A for motor switching duty, and compliant with IEC 60947-6-1 (Class PC), CE, and PC (ME01) certifications, this unit is manufactured in Finland. Available as surplus stock through WeSellStocks.co, it is a high-specification procurement item for EPC contractors, generator system integrators, and MRO buyers across the USA, UAE, and worldwide industrial markets.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e ABB\u003cbr\u003e\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Motorized Changeover Switch \/ Automatic Transfer Switch (ATS)\u003cbr\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e OTM250E4CM230C\u003cbr\u003e\u003cstrong\u003eIndustry Category:\u003c\/strong\u003e Power Distribution \/ Automatic Transfer Switching \/ Critical Power Systems\u003cbr\u003e\u003cstrong\u003eRated Operational Current (Ie):\u003c\/strong\u003e 250A\u003cbr\u003e\u003cstrong\u003ePoles:\u003c\/strong\u003e 4-pole\u003cbr\u003e\u003cstrong\u003eFrequency:\u003c\/strong\u003e 50–60 Hz\u003cbr\u003e\u003cstrong\u003eRated Voltage — AC-31B (resistive load):\u003c\/strong\u003e 415V \/ 250A\u003cbr\u003e\u003cstrong\u003eRated Voltage — AC-33B (motor load):\u003c\/strong\u003e 415V \/ 250A\u003cbr\u003e\u003cstrong\u003eRated Voltage — AC-23A (motor switching, IEC 60947-3):\u003c\/strong\u003e 690V \/ 250A\u003cbr\u003e\u003cstrong\u003eRated Thermal Current (Ith):\u003c\/strong\u003e 250A (50–60Hz)\u003cbr\u003e\u003cstrong\u003eImpulse Withstand Voltage (Uimp):\u003c\/strong\u003e 12kV\u003cbr\u003e\u003cstrong\u003eShort-Time Withstand Current (Icw):\u003c\/strong\u003e 15kA \/ 100ms\u003cbr\u003e\u003cstrong\u003eMaking Capacity (Icm):\u003c\/strong\u003e 30kA\u003cbr\u003e\u003cstrong\u003eActuator Control Voltage:\u003c\/strong\u003e 230V AC (confirmed from part number suffix CM230C)\u003cbr\u003e\u003cstrong\u003eOperation Modes:\u003c\/strong\u003e Automatic (motorized) and Manual (confirmed from \"Man.\" label on actuator module)\u003cbr\u003e\u003cstrong\u003eUtilization Class:\u003c\/strong\u003e Class PC\u003cbr\u003e\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Panel mount — DIN rail or direct fixing\u003cbr\u003e\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e Finland\u003cbr\u003e\u003cstrong\u003eStandards \/ Compliance:\u003c\/strong\u003e IEC 60947-6-1 (Class PC) | IEC 60947-3 | CE | PC ME01\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe ABB OTM250E4CM230C motorized changeover switch is used in automatic transfer switch (ATS) systems to provide seamless switching between a primary mains supply and a standby generator or secondary power source in hospitals, data centers, commercial buildings, industrial plants, and critical infrastructure facilities. The motorized actuator (230V AC control voltage) enables remote and automatic operation triggered by voltage monitoring relays or ATS controllers, while the manual override ensures safe local operation during maintenance. Its 4-pole configuration switches all live conductors including neutral, making it compliant with TN-S earthing system requirements. This is a standard specification item for generator system integrators, EPC contractors, and critical power procurement teams managing high-availability electrical infrastructure globally.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe ABB OTM250E4CM230C motorized changeover switch is available through WeSellStocks.co as a surplus unit, serving generator system integrators, critical power contractors, and industrial MRO procurement teams across the USA and UAE.
