  • Notas:
  • *1Interchangeable earth leakage relays can be freely combined with relays and our ZCTs.
    However, 30mA sensitive products (excluding NV-ZHA/ZLA) are only available in combination with the ZT15B, ZT30B, and ZT40B.
  • *2Indicates the UL control voltage. This product is simultaneously marked for UL (cURus) and JIS.
    JIS voltage indication is 100/200V selectable for 120/240V selectable, 200/415V selectable for 240/440V selectable, and 460V for 480V.
    Please specify "UL/JIS" when ordering.
  • *3Indicates the UL control voltage. This product is simultaneously marked for UL (cURus) and JIS.
    CE voltage indication is 120/230V selectable for 120/240V selectable, 230/440V selectable for 240/440V selectable.
    Please specify "UL/JIS" when ordering.
  • *4This is a high-speed/time-delay switching type. The product is marked with the maximum value.
  • *5Operating time ranges from 0,15 to 0.45s for 0.3s and 0.45s, 0,6 to 1.0s for 0.8s and 1.0s, and 1,2 to 2.0s for 1.6s.
  • *6Can be combined with the interchangeable ZCT with a primary conductor. Refer to the general catalog for details.
  • *7Not UL certified.
  • Remarks:
  • 1Relays with ratings shown in parentheses ( ) are manufactured to order.
  • 2The CE marking is a self-declaration for the purpose of tripping the MCCB in the event of ground fault when combined with a Mitsubishi Electric’s MCCB with CE marking (with a shunt trip device).
  • 3NV-ZBA/ZSA/ZAA/ZP
    Control voltage Applicable circuit voltages Voltage fluctuation range where
    the earth leakage protection can operate.
    100 V 100/110V 80 to 121V
