Barber Colman CB41-01240-025-1-00 Power Controller

Barber Colman CB41-01240-025-1-00 Power Controller is a single-phase control device engineered to modulate power to 240 VAC loads with smooth, stepless adjustment. As part of Barber Colman’s CB41 family, the unit targets resistive loads typical of industrial heating and process-control equipment, where gradual power changes are preferable to abrupt on/off switching. The CB41 family is historically described as providing stepless power control for resistive loads and, in broader practice, accepts supply voltages across a wide range (noted in older CB41 documentation as 3 to 240 V and capable of AC or DC operation on some configurations). This model’s designation—CB41-01240-025-1-00—identifies its membership in that lineage and its 240 VAC operating environment, making it suitable for installation in control panels or equipment that require controlled heat, drying, or similar processes without sudden power surges. Typical applications include industrial ovens or heaters, laboratory test fixtures, and machines that rely on precise power delivery to resistive elements. The product carries the Barber Colman brand, a long-standing name in automation controls now associated with Invensys lineage, and CB41 devices are recognized for enabling reliable, adjustable control of load power in compact, field-installable packages.
