Single Phase 15a Breaker

NBT1-63 high breaking miniature circuit breaker (air switch) is suitable for protecting short circuit and overload of circuit, suitable for lighting distribution system or motor distribution system. It has beautiful appearance, light weight, excellent performance, reliable breaking capacity, quick tripping, high guide rail installation, high flame retardant and impact resistant plastic shell and parts, long service life, mainly used for AC 50 Hz, rated power When the voltage is 400V and the rated current is 63A, the overload and short-circuit protection of the line can be realized. At the same time, the electrical device and lighting line can be switched on and off infrequently under normal conditions.

Product Specification

Product Features

1. Far beyond the standard service life; mechanical life: 20000 times; electrical life: 10000 times (standard: 10000 and 4000 respectively).

2. Side opening design, more convenient assembly of accessories.

3. The installation view and wiring board are molded to facilitate user perception.

4. Fillet design to prevent users from scratching.

Sand filling machine: the frequency and duration of sand shaking are controlled by numerical control to achieve a certain density of sand compactness step by step. The fuse sand plays an arc extinguishing role, and the internal sand compactness is very important.

Vacuum oven: make the inside reach the vacuum state, draw to the negative pressure of 0.1 PA, so that the excess curing inside the product is discharged, and do the preliminary work for curing.

Drying numerical control heating oven: control temperature module, can automatically step in the required time temperature, heat preservation; so that the product can achieve uniform temperature, so that the internal completely solidified into dry solid.

Low voltage fast fuse test bench: the independent laboratory can independently test the fuse test and temperature rise dissipation test of the product, and adjust the design scheme according to the test results until it is qualified and put into production.

The company has always been adhering to the concept of "let users use better", and has always been committed to providing the latest and best products for global users. Promote the development of electrical technology in China. The company provides safe and reliable DC circuit breakers and other products for China rail transit, photovoltaic power station and other projects.

FAQ

Q1: How many times can a circuit breaker trip?

A1: An electrician is coming to replace the cutoff (containing fuses) with a simple lever cutoff. In discussing this he said that a circuit breaker should not be allowed to trip more than 4 or 5 times before being replaced.

Q2: At what age should a house be rewired?

A2: If a property is more than 30 years old and has the original wiring, it is likely to need updating, at least in part, to meet modern standards, including replacing the fuse box with a modern consumer unit. A sign a rewire is necessary, is dated rubber, fabric or lead-insulated cabling.

Q3: Can you rewire a house without removing walls?

A3: Thankfully, there is an alternative to tearing down walls. It is possible to rewire your home without removing the drywall. The method used by the electrician is to find a crawlspace to feed the wire through the wall.

Q4: What is the process of rewiring a house?

A4: Rewiring a property is messy, disruptive work. It happens in two stages: first fix, when cables and wiring are installed, and second fix when everything is joined up or made 'live', when the front faces of sockets, switches and lights are fitted. You can then consider the lighting and switches required.

Q5: Should I upgrade my breaker box?

A5: The recommended amount for modern builds and upgrades is 200 amps. If you are planning on a remodeling project or adding on to your home, you may need to replace your panel entirely. If you are experiencing frequently tripping breakers, speak with an electrician about adding more power.
