NOFUEL 3RT1025 ACコンタクタ 3極 17A AC-3 7.5kW 400V S0フレーム Siemens 3RT1025シリーズの代替品

製品説明

NOFUEL 3RT1025 is S0 frame 3-pole AC power contactor fully dimensionally interchangeable with Siemens original 3RT1025 series, designed for frequent on-off control of three-phase AC motors and industrial resistive loads under AC-3 duty cycle. It delivers rated operational current of 17 A with matched motor power 7.5 kW at 400 V, equipped with built-in 1NO auxiliary contact for equipment running signal feedback. This contactor adopts screw terminal wiring, supports standard 35mm DIN rail and direct screw mounting, features IP20 front touch safety insulation, and complies with CE certification. Multiple AC coil voltage options (24V/110V/120V/220V/240V/480V) are available, widely applied in machine tools, water pumps, ventilation fans and medium-sized automation control cabinets as cost-effective replacement for discontinued original Siemens contactors.

標準機能

• 完全な機械的互換性： Identical S0 housing dimension, terminal layout and mounting hole position with Siemens 3RT1025 for direct plug-and-play replacement.
• Stable 3-pole main contact system: Three normally open alloy main contacts with anti-arc design for frequent motor start-stop switching.
• 一体型1NO補助接点：回路インターロックおよび動作状態信号出力用の、工場出荷時に取り付けられた単一のNO補助接点。.
• Multi-voltage AC coil options: Optional coils cover 24V to 480V AC to match global industrial control power supply standards.
• Dual mounting solution: Supports snap-on assembly on 35mm DIN EN rail and independent screw fixing for flexible cabinet layout.
• IP20 safety insulation: Insulated front terminal cover prevents accidental contact with live conductive parts during maintenance.
• Long mechanical service life: Optimized electromagnetic structure realizes up to 10 million mechanical switching cycles for continuous industrial operation.
