Protection and release characteristics

C-curve release: Magnetic release action within the range of 7In~10In

Positive polarity disconnection indication: The green bar displays full pole disconnection, indicating safe operation

Current limiting: Quickly disconnect in case of fault to protect the load

Quick closure: independent of handle speed, extending lifespan

Isolation function: meets the isolation requirements of IEC60947-2

Temperature reduction (25 ℃ benchmark)

As the ambient temperature rises, the rated current needs to be reduced according to the coefficient in the table

Multiple units installed side by side in a small cabinet require an additional multiplier of 0.8

Extreme configuration and fault protection

The grounding system is divided into three categories: grounded/ungrounded/midpoint grounded

24V~250V: 1P/2P optional; 2P is required for voltages greater than 250V

Fault types A/B/C correspond to different polarity protection and disconnection requirements

Key issues

Question 1: What are the magnetic release parameters of C60H-DC? What is the action range of the C-curve?

Answer: The magnetic trip current is 8.5In ± 20%; The electromagnetic trip action range of the C-curve is 7In~10In, used for conventional DC circuit overload and short circuit protection.

Question 2: What are the mandatory safety requirements for the wiring of this product? What are the consequences of violating?

Answer: Polarity must be strictly observed, reverse connection poses a risk of fire and electric shock; 2P series connection for the US power grid requires the use of * * ≥ 30cm * * cables; The wiring torque should meet the standard (2.5/3.5N · m). Violation may result in burning, short circuit, and protection failure.

Question 3: What are the core differences between the P and 2P models in terms of voltage, breaking capacity, and application scenarios?

Answer: 1P rated voltage 250V DC, breaking 5kA, used for ≤ 250V unipolar grounding system; 2P rated 500V DC, maximum breaking 20kA, used for>250V or ungrounded bipolar DC systems, with a wider range of applications and more complete protection.
