Combined terminal block JXB SAK 2.5EN 4EN 6EN 10EN 16EN 25EN 35EN 70EN Din Rail Weidmuller JXB SAK Feed through terminal block

   
JXB / SAK series terminals block

The terminal block is a kind of accessory product used to realize electrical connection, which is industrially divided into the category of connectors. The terminal is used to facilitate the connection of the wire. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends to insert the wire. There are screws for fastening or loosening. For example, two wires, sometimes Need to connect, sometimes need to disconnect, then you can use the terminal to connect them, and can be disconnected at any time, without having to weld them or entangled together, it is very convenient and fast.



 

Characteristics:
1. Reasonable installation design, strong versatility, SAK type can be installed.
2.Small size, full specification, JXB series high current terminals use reinforced accessories to install steel wire crimping frame and breakout board technology to ensure reliable contact.3.Bckets in beige and grey,the connecting-ground pedestal uses yellow and green color with more modern sense.

Technical FAQ & Selection Guide

💡 Frequently Asked Technical Questions & Selection Guide

Pure engineering specifications, tripping curve parameters, and electrical selection guidance for panel builders and system designers.

Voltage & Load Sizing

How to verify rated operational voltage, frequency, and load duty cycle?

A

Verify that the nominal line voltage (AC 230V single-phase or 400V/415V/690V three-phase at 50/60Hz, or DC voltage ratings) falls within the continuous maximum operating limits of the device. Check duty cycle ratings (continuous vs intermittent duty) to ensure thermal stability under full load.

Protection & Environment

What ingress protection (IP Rating) and environmental enclosures are recommended?

A

For clean indoor electrical rooms, standard IP20 modular DIN-rail housings are recommended. For outdoor, industrial washdown, or dusty environments, mount components inside weatherproof enclosures rated IP65/IP66 with UV-resistant polycarbonate or powder-coated steel enclosures equipped with compression cable glands.

Selectivity & Grading

How to ensure upstream and downstream coordination in power distribution boards?

A

Ensure proper discrimination by grading current thresholds and tripping time delays: upstream devices should have higher current ratings and intentional short-time delays (Class S), allowing downstream branch MCBs to clear localized faults without blacking out the entire facility.

Installation & Mounting

What mounting rails, busbars, and spatial clearances are required?

A

Components mount on standard symmetrical 35mm DIN rail (EN 60715 / TH35-7.5) or backplate screw fixings. Maintain recommended top/bottom ventilation gaps (typically 30–50mm) to ensure unrestricted air convection, and use standard pin/fork comb busbars to minimize contact resistance and wiring errors.

Conductor & Torque Sizing

What conductor sizes and terminal tightening torques should be applied?

A

Select copper or aluminum conductor cross-sections complying with IEC 60364-5-52 current-carrying capacity tables based on continuous load. Always use a calibrated torque screwdriver or torque wrench to tighten terminal screws to the manufacturer-specified torque to prevent hot-spot degradation and loose connections.
