Description

XB7NA21 XB7NA31 XB7NA42 flush XB7-EA21 Black 1NO XB7-EA31 Green 1NO XB7-EA42 Red 1NC XB7 Pushbutton

XB7 monolithic push button operates with a spring return / impulse mechanism and screw clamp terminals. It is easily installed into standard 22mm diameter panel cut-outs and connected to control circuits with classic screw-clamp connections. Its schematic is clearly distinguishable thanks to clear colors and markings, minimizing errors during initial wiring and later maintenance operations. It is impact resistant, dust resistant, water resistant and vibration resistant thanks to its IP65, making it ideal for operation in harsh environments. It has a double insulated plastic bezel. Its wide range of operating temperatures from -25°C to 70°C allows versatility in usage of product.

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?

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?

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?

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?

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?

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.
