Modular attachments and configuration

Function expansion module

N-pole module (N-P1X/P3X/P5X series): early closing/delayed breaking, can be installed on the left/right side, with breaking capacity consistent with the main contact

Auxiliary contact module (HI11-P1X/P3 series): 1 normally open+1 normally closed contact, compatible with signal feedback and control circuit expansion

Operation and protective accessories

Operation accessories: Thumb handle (black/red, in accordance with IEC/EN 60204-1 emergency stop standard), extension rod (up to 4 × 25mm extension), interlock mechanism (door interlock/cover interlock)

Protective accessories: terminal cover, padlock device (up to 3 padlocks), insulated distribution box (CI-K series)

Identification attachments: Emblem (including different switching angle identification), front panel with lettering attachment (ZFS series)

Configuration principle: Accessories should match the switch model and installation method. For example, the P1X surface installation model only supports the installation of N-pole modules on the left side

Key technical data

Lifespan and operating frequency

Mechanical lifespan: TX series 400000 on-off cycles, PX series 100000 on-off cycles

Electrical lifespan: Under AC-3 load, the longer the breaking current, the shorter the lifespan (e.g. about 100000 times at T0X 20A)

Maximum operating frequency: 3000 times/hour (TX series), 50 times/hour (PX series)

Breaking ability (AC-3, cos φ=0.35)

T0X (20A): 100A at 380V, 110A at 400V

P3X-100 (100A): 760A at 400V, 520A at 690V

P5X-175 (175A): 900A at 400V, 340A at 690V

Wiring ability

Solid/Twisted Wire: P1X supports 1.5-6mm ², P5X supports 50-70mm ²

Flexible cord (with metal sleeve): P3X supports 1.5-25mm ², P5X supports 16-70mm ²

Tightening torque: M4 terminal 1.6Nm, M10 terminal 14Nm

Ordering and selection information

Model composition: adopting modular coding, including series, current level, installation method, accessory configuration and other information (such as T0X-1-8200/E represents T0X series, 1 contact module, on-off switch, flush installation)

Standard packaging: 1 piece/box for most models, 5 pieces/10 pieces/25 pieces/box for accessories (such as handles and modules)

Non standard customization: A F02 customization form is required to specify the requirements for contact sequence, switching angle, spring reset, etc. For repeated orders, only the contact number and country identifier need to be specified

List index: The document appendix contains a complete material number model correspondence table (92 pages in total), covering the entire series of standard and non-standard products, making it easy to quickly query order numbers
