This surge protector is designed and manufactured by Phoenix Contact, a renowned German technology company with a global presence and a strong reputation for producing high-quality electrical components.

This surge protector is housed in a compact, rugged box measuring 68.5 x 53 x 26.5 mm (2.7 x 2.1 x 1.0 inches) and weighing just 63 grams (2.2 ounces), making it an excellent choice for installation in confined spaces or portable applications. The box is made of impact-resistant plastic, ensuring durability and protection against environmental hazards.

The PT3-hf-12DC-ST surge protector features four 12V DC input/output (I/O) channels, each with a current capacity of up to 3A. This makes it suitable for use with various low-voltage devices such as sensors, actuators, and communication modules. The surge protector is equipped with a polymeric positive temperature coefficient (PTC) resettable fuse on each channel, providing an additional layer of protection against short circuits and overloads.

One of the key features of this surge protector is its high surge capacity. It can withstand and protect against surges up to 3,000V peak and 2,000V working voltage, ensuring that sensitive equipment remains safe from damage caused by electrical transients. The PT3-hf-12DC-ST also offers excellent overvoltage protection, as it is rated for continuous operation up to 15V DC.

The surge protector is easy to install, with a simple push-in terminal design for quick and secure connection of wires. The terminal area is generously sized, accommodating wires up to a diameter of 4.5 mm (0.18 inches). The input and output leads are 10 cm (4 inches) long, providing sufficient length for most installation scenarios.

The PT3-hf-12DC-ST surge protector is suitable for use in a wide range of industrial applications, including automation, process control, and communication systems, where reliable power protection is essential. It is also suitable for use in harsh environments, as it is rated for operation in temperatures between -25 C and 70 C (-13 F and 158 F).

In summary, the Phoenix Contact PT3-hf-12DC-ST surge protector box, model number 2858043, is a robust and versatile solution for protecting 12V DC equipment from electrical surges and transients. It offers a high surge capacity, easy installation, and a rugged design, making it an ideal choice for various industrial applications.
