Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR13BT/UCV is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT only
• Switch function: On-Off-On only
• Current rating: 15A (AC/DC) minimum
• Voltage rating: 125V AC and 30V DC minimum
• Mounting type: Panel Mount, Snap-In
• Actuator type: Concave (Curved)
• Actuator color: Ivory
• Termination style: Screw Terminal
• Ingress protection: IP67 minimum
• Panel cutout dimensions: Rectangular 34.20mm x 17.20mm
• Operating temperature range: -25°C to 85°C minimum
• Mechanical life: 30,000 cycles minimum
• Electrical life: 10,000 cycles minimum
• Approval agencies: EN and UL certification required

The WR13BT/CUL meets all substitution criteria and is classified as a direct equivalent part.
