3 Phase Circuit Breaker Switch

NBT1-63 series miniature circuit breaker is composed of the outer end of the material, the over-current release, the operating mechanism, the contact and the arc extinguishing system. It is suitable for overload and short-circuit protection of circuit, lighting and power equipment in circuits with sub AC 50z or 60Hz rated voltage of 280 / 400W and rated current of 63A and below. It can also be used for circuit failure and infrequent on-off conversion of equipment under normal conditions.

Product Specification

Product Features

1. The breaking capacity of 63A product is increased to 6ka, and the product performance is better

2. As many as 7 kinds of independent installation accessories, the expansion function is stronger, to meet the diversified needs of customers

3. The contact status indicator window is added to the whole series of products to reliably indicate the opening and closing status of the circuit breaker.

4. The whole series of unified industrial design, more beautiful appearance

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 specializes in the production of low-voltage components and components products. The company has established a long-term and stable cooperation relationship with many enterprises to provide supporting products. Since its establishment, the company has been committed to the research and development, production, manufacture and sales of products with excellent quality and reliability, with rich production experience and strong supporting capacity, providing services for domestic and foreign transmission and distribution industry and from many large enterprises.

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.
