Electronic Fuse Circuit

This circuit is an adjustable electronic circuit breaker that features a toroidal transformer designed to sense a 60-Hz load current. The transformer, labeled as T1, has a two-turn winding for the primary side and 100 turns of #30 gauge wire for the secondary side. A high-low range switch allows selection between current ranges of 0.1 to 6 A or 1 to 12 A. The primary winding of T1 carries the full load current and voltage, and both T1 and the relay RY1 require appropriate insulation.

The adjustable electronic circuit breaker circuit utilizes a toroidal transformer (T1) to monitor the load current in a 60-Hz AC system. The design incorporates a primary winding with two turns, which is capable of handling the full load current. The secondary winding consists of 100 turns of #30 gauge wire, allowing for adequate voltage transformation and current sensing.

The circuit includes a high-low range switch that enables the user to select between two current ranges: 0.1 to 6 A and 1 to 12 A. This feature provides flexibility for various applications, ensuring that the circuit breaker can operate effectively across different load conditions. The switch alters the sensitivity of the circuit, adjusting the threshold at which the breaker will trip in response to overcurrent conditions.

Insulation is a critical aspect of the design; both the primary winding of T1 and the relay (RY1) must be suitably insulated to prevent electrical faults and ensure safe operation. The relay acts as the switching mechanism that interrupts the circuit when an overcurrent condition is detected, providing protection against potential damage to the connected load.

In summary, this adjustable electronic circuit breaker circuit is designed for reliable performance in monitoring and protecting electrical loads by utilizing a toroidal transformer for current sensing and a relay for circuit interruption. Proper insulation and component ratings are essential for maintaining the integrity and safety of the circuit. Basically, this circuit is an adjustable electronic circuit breaker, containing a toroidal transformer that senses 60-Hz load current. Tl has a two-turn winding for primary, and 100 turns of #30 gauge wire for the secondary. A high-low range switch selects 0.1 to 6 A or 1 to 12 A. The primary winding of Tl carries full load current and voltage; should be suitably insulated, as should be RY1. 🔗 External reference
