C60H-DC supplementary protectors are designed per UL 1077 to provide overcurrent protection within appliances or electrical equipment, where a branch circuit protection is already provided or not required. Devices are designed for direct current (DC) control circuit applications.

Features

• 1- and 2-Pole Construction
• 0.5–63 A (up to 40 A in UL 1077)
• DC Voltage

Nominal: 1-pole 250 Vdc, 2-pole (wired in series) 500 Vdc
Operating Voltage: 1-Pole 12–250 Vdc, 2-Pole 12–500 Vdc
High Voltage Withstand (Uimp): 6 kV

• Interrupting Rating: 5 kA at 250 Vdc and 500 Vdc
• Trip-Free Mechanism

Contacts cannot be held in the I - ON position when the supplementary protector is tripped automatically.

• Positive Break Indication

Along with the international I/O markings, a green mechanical indication on the front face of the supplementary protector shows that all poles are open.

• Fast Closing

Allows increased service life of the supplementary protectors.

• Limits Let-Through Current

Prevents loads from getting damaged during short circuit by fast opening of the contacts.

• Endurance (O-C)

— Electrical

3,000 cycles (where L/R=2ms)
6,000 cycles where the circuit is resistive

— Mechanical

20,000 cycles

• Thermal-Trip Element

Thermal-trip elements are factory calibrated at 25°C/77°F

• Magnetic-Trip Element

Curve C: Magnetic release operates between 7 and 14 times ampere rating.

• Compliance with International Standards

— UL1077
— IEC 60947-2
— EN 60947-2
— CCC / GB 14048.2
— CE marked

• System Accessories and Electrical Auxiliaries

Same as used in Multi 9 C60 range (see 0860CT0201 for details).

• Mounting and Connections

— DIN-Rail Mounting
— Standard box lug connection and optional field-installable ring tongue terminal kit.
