Notes:
1. Cold resistance measured at less than 10% of rated current at 25°C
4. For 15A rating with 10kA@86VDC IR, please use suffix “S” for ordering. Refer to Part Numbering System for
reference.
5. 15A rating with suffix “MRS” is UL certified with 10kA at 86VDC. This is also reflected on page 3.
2. Agency Approval Table Key: X = Approved or Certified, P=Pending and Blank=Not Approved.
3. I2t values stated for 8msec opening time.
