Model BEM38-20X/31 — Key electrical specifications Nominal voltage: 440 V Insulation voltage (Ui): AC 660 V Rated/working current (Ith): 10 A What this product does and why you need it Provides a clearly specified electrical component for systems that operate at or near 440 V. The 10 A working current rating supports stable operation of small power circuits and control lines. The AC 660 V insulation rating gives a safety margin for dielectric isolation between live parts and the enclosure or adjacent circuits, reducing risk of breakdown under transient or elevated-voltage conditions. Maintains reliable performance where a well-defined voltage and current rating is required for compatibility, replacement, or system design. Key benefits and problem solving Predictable performance: Specified Ith and Ui let you match the component to circuit protection and load requirements without guesswork. Safety and isolation: AC 660 V insulation rating reduces the chance of insulation failure in environments with voltage spikes or higher system voltages. Compatibility and replacement: Use this exact model BEM38-20X/31 when replacing components or specifying parts for equipment that requires a 440 V nominal rating and 10 A working current. Important attributes Function: Electrical device specified for operation at nominal voltage 440 V with a rated working current of 10 A and an insulation voltage of AC 660 V. Compatibility: Intended for electrical systems, control cabinets, or equipment that require components rated at 440 V nominal and up to 10 A continuous current. Performance: Designed to handle steady currents up to 10 A while providing insulation protection up to 660 V AC. Safety: Insulation rating supports separation between live conductors and accessible parts in accordance with the component’s Ui specification. Practical use scenarios Industrial control panels: Use BEM38-20X/31 in subcircuits or control circuits where panels are supplied by 440 V systems and components are specified for 10 A operation. Small motor control or auxiliary circuits: Suitable where control relays, pilot devices, or auxiliary circuits draw currents around or below 10 A and must be compatible with a 440 V nominal supply. Equipment maintenance and replacements: Direct replacement option when an exact model and its electrical ratings (440 V nominal, AC 660 V insulation, 10 A working current) are required to maintain original system specifications. Installation and compatibility notes Confirm system nominal voltage and required current capacity before installation to ensure full compatibility with the BEM38-20X/31 ratings. Coordinate with protective devices (fuses, breakers) sized appropriately for a 10 A working current and the characteristics of the connected load. Follow applicable local electrical codes and manufacturer installation instructions for safe and compliant use.
