1492-D1C200

The 1492-D1C200 by Allen Bradley is a specialized supplementary protector providing critical overload and short-circuit protection for electrical circuits. This unit handles a current rating of 20 Amps and is configured as a single pole, making it a versatile choice for various installations. Its operational characteristics are defined by a Curve C trip type, suitable for handling specific types of inrush currents without nuisance tripping.

This protector is designed to operate effectively at frequencies ranging from 50 Hz to 60 Hz, fitting well within standard electrical systems. It is rated for Pollution Degree 3, highlighting its robustness in environments where pollutants may be present. The unit exhibits significant resistance to mechanical shocks, able to endure shocks of up to 25 G with two impacts lasting 13 milliseconds each. Additionally, its vibration resistance specification of 5G allows it to maintain performance over 20 cycles at varied frequencies while loaded at 0.8 times its rated current.

Terminal connections are facilitated through dual terminal types, enhancing wiring flexibility and simplifying connections. The back terminal slot is designed for a bus bar cross-section of 10 mm2, ensuring reliable current transfer. The mounting method utilizes a 35 mm DIN rail, compliant with EN 60715, and allows for quick attachment via a fast clip mechanism.

The durability of the 1492-D1C200 is reinforced through its electrical endurance rating, which offers 6,000 operations in both AC and DC applications. This protector's cycling is rated at one operational cycle—1 second on followed by 9 seconds off, providing reliability for long-term usage in demanding electrical settings.
