Interruttore automatico magnetotermico Legrand 49754 larghezza 75 mm profondità 115 mm altezza 60 mm

Legrand 49754 is a compact circuit breaker designed to protect electrical circuits from overloads and short circuits. With overall dimensions of 75 mm width, 115 mm depth and 60 mm height, this device is intended for installation where space is limited but reliable protection is required. The product is produced by a recognized manufacturer and integrates into distribution boards and electrical enclosures in residential, commercial or light-industrial environments.

Advantages

The circuit breaker provides reliable thermal-magnetic protection and is constructed to meet standard safety and durability requirements. Its compact footprint simplifies mounting in crowded panels and cabinets. The design ensures clear identification of terminals and contributes to straightforward wiring and maintenance. Durable materials and consistent trip characteristics reduce the likelihood of nuisance trips while ensuring fast interruption in fault conditions.

Key specifications

How to use

Install the circuit breaker in the distribution board according to local electrical codes and the installation guidelines provided by the system designer. Ensure power is isolated before making connections. Tighten terminals to the specified torque and verify correct phase and neutral wiring. After installation, switch the breaker on to confirm normal operation and perform a controlled test of protected circuits to ensure proper tripping under fault conditions. Routine visual inspections and functional tests should be scheduled as part of normal maintenance.

Recommendations

Use this device only within its rated electrical parameters and in environments that meet the temperature and humidity limits specified by the electrical installation standards. Replace or service the circuit breaker if it shows signs of mechanical damage, excessive heating or inconsistent tripping behavior. For final selection and settings, consult a qualified electrician to match the breaker characteristics to the application.
