The Schneider Electric DT40 circuit breaker is designed for reliable overcurrent protection in single-phase plus neutral applications. This 1-pole + neutral device features a 2A current rating and a C curve tripping characteristic, making it suitable for protecting circuits with moderate inrush currents, such as those found in control panels and distribution boards.

Technical details

• Series: DT40
• Configuration: 1 Pole + Neutral (1P + N)
• Current Rating: 2 Amperes (2A)
• Tripping Curve: C Curve
• Interrupting Capacity: Verify against manufacturer datasheet for specific rating.
• Voltage Rating: Verify against manufacturer datasheet for specific AC/DC voltage.
