Cylindrical fuse link CH14x51 aM 16A/690V 002652030

Cylindrical fuse link CH14x51 aM 16A/690V is a safety element for electrical installations, protecting against the effects of overloads and short circuits. It is a component designed to work with alternating current (AC) circuits with a voltage of up to 690V. This fuse link, with dimensions of 14x51 mm, is characterized by an aM characteristic, which means it is optimized for protecting electric motors – allowing for short-term current overloads that occur during motor start-up, without unnecessarily disconnecting the circuit.

Application and functionality

Cylindrical fuse links, such as the CH14x51 aM model, play a key role in ensuring the safety of electrical installations. They are widely used in industry, construction, and commercial and domestic installations. The aM characteristic makes them particularly useful in circuits powering motors – allowing for momentary current surges during device start-up, while providing effective protection against more serious failures caused by short circuits or overloads. This minimizes the risk of equipment damage and downtime.

Construction and characteristic features

CH14x51 fuse links are made of high-quality materials – a body made of C110 or C410 porcelain provides electrical insulation and mechanical resistance. Contacts made of CuZn28 with the addition of Ag (silver) guarantee good electrical conductivity and durable connections. Compact dimensions (14x51 mm) allow for installation in limited spaces. It is worth noting the precise dimensions: outer diameter 22.2 mm (+/- 0.1 mm), length 58 mm (+/- 0.1 mm). These fuse links are available in packages of 10 or 500 pieces, and their unit weight is approximately 18.6 g.
