IEC 60898-1 Power Load Cabinet For Circuit-Breakers clause 9.11
Test
Standards & Clauses:
The test equipment conforms to the standard requirements of IEC
60898-1:2015 Electrical accessories-Circuit-breakers for
overcurrent protection for household and similar installations-Part
1: Circuit-breakers for a.c.operation clause 9.11 Verification of
machnical and electric endurance, IEC 61009-1:2012 and etc.
Product Information:
This equipment is designed to provide adjustable load voltage,
current, and power factor for testing mechanical and electrical
contact systems. It is ideal for conducting switching capacity and
endurance tests on switches used in household and similar fixed
electrical installations. Additionally, it is well-suited for
performing breaking capacity and operating life tests on household
plugs and sockets, as well as electrical stress tests for lamps and
other related applications.
Working Principle:
The load cabinet delivers a three-phase power output with
corresponding three-phase load input, offering selectable load
types including resistive, inductive, or capacitive (fluorescent
lamp simulation) loads, or a combination of the three.
Load current range: 8–130A, adjustable manually
Output voltage range: AC 10–400V, adjustable manually
Power factor range: 0.3–0.999, electrically adjustable
The equipment features a streamlined design, optimized structure, and user-friendly operation, making it an excellent solution for laboratories and production
environments requiring flexible and precise load testing.
Features:
The load cabinet features an integrated steel frame structure
combined with Toyota white sealed panels for enhanced durability
and aesthetics. The upper front section houses the control
interface, which includes the main power switch, digital displays
for output current, voltage, and power factor, load power switch,
various status indicators, start/stop buttons, capacitance
selection switch, load type selector, and alarm indicators, among
others.
The lower panel is equipped with dedicated adjustment knobs for
voltage, current, and inductance control across each channel,
allowing precise and flexible operation. Each load cabinet is
designed with three-in-one functionality, supporting resistive,
inductive, and capacitive (fluorescent lamp simulation) loads,
easily switched via the integrated selector.
Internally, the cabinet utilizes a high-efficiency forced air
cooling system to ensure stable operation during prolonged testing.
Connection terminals are provided at the rear and lower sections of
the cabinet, facilitating direct connection to switch, plug, and
socket life testing systems. During operation, the cabinet delivers
adjustable current, voltage, and power output to meet diverse
testing requirements.
