Manual Reset Thermostat

Manual reset thermostat KSD301

The Xucheng Manual Reset Thermostat (KSD301 series) is an over-temperature protection device designed with bimetallic strip technology. It inhibits aberrant device restarts via a manual reset mechanism, making it ideal for applications demanding exceptional safety and reliability. Certified by VDE, UL, TUV, and CQC, this Manual Reset Thermostat ensures precise temperature regulation and overload protection for domestic appliances, industrial machinery, and specialized systems.

Fundamental Parameters and Accreditations
Rated Voltage: AC 250V (50-60Hz) / AC 125V (UL approved)

Rated Current: 10A/16A/20A (resistive load) / 15A (UL AC125V resistive load)

Temperature Range: 0-210℃ (customizable)

Breaking Capacity: AC 1500V withstand voltage (1-minute test)

Certifications: VDE EN 60730, UL 60730, TUV GS, CQC GB 14536

Safety Attributes: Manual reset design complies with ISO 13849-1, preventing automatic restart risks.

Operational Mechanism and Technical Benefits
Bimetallic Strips for Precision

High-sensitivity bimetallic strips actuate at preset temperatures, disconnecting circuits instantly.

Manual Reset Requirement: Post-cooling, reactivation requires manual button/knob engagement, eliminating accidental restarts.

Industrial-Grade Durability

Housing: PA66 engineering polymer (-20℃ to +85℃ resistant).

Contacts: Silver-plated copper alloy (<50mΩ resistance, 3x corrosion resistance).

Environmental Resilience: Passes 1500V AC surge tests and IEC 60068-2-6 vibration trials.

Safety & Efficiency

Malfunction Lock: Forces shutdown during anomalies, preventing fires or equipment damage.

Energy Optimization: Reduces erroneous cycling, saving 15-20% energy vs. auto-reset solutions.

Key Applications

Household: Electric water heaters, coffee makers (e.g., KSD301-10A/250V NC).

Industrial: Motor drives, heating furnaces (e.g., KSD301-16A/250V NO).

Renewables: Battery packs, charging stations (e.g., KSD301-15A/125V UL model).

Temperature: Match to system's max safe limit (e.g., 120℃ for motors).

Contact Type: NC (heating) or NO (cooling).

Installation: Fixed/movable flange or extended probe for remote monitoring.

Positioning: Mount near monitored components (e.g., motor windings).

Electrical Connection: Torque terminals to 4-6 N·m; ensure proper grounding.

IP65 Enclosure: Mandatory for outdoor/humid environments.

Maintenance:

Monthly inspections for contact integrity.

Annual calibration (±5℃ tolerance).

Proactive replacement at cycle limits (e.g., 100,000 cycles).
