CRYDOM

CRYDOM, a brand of Sensata Technologies, is a manufacturer of solid-state relays (SSRs) and related thermal management components. Founded in the United States, CRYDOM has been a reference in the SSR market since the 1970s, focusing on semiconductor-based switching solutions for industrial applications. The product line includes panel-mount, DIN-rail, and PCB-mount SSRs, as well as dual SSRs, heat sinks, and controllers. Output devices span triac and SCR types, with current ratings from 10 A to 50 A and voltage ranges up to 530 V AC. Build standards emphasize finger-safe enclosures on many models, screw-clamp or quick-connect terminations, and Form A (SPST-NO) switch configurations. Thermal resistance values for heat sinks, such as the HS151DR at 1.5°C/W, are specified to aid system design. 3G Electric supplies CRYDOM SSRs and heat sinks globally, offering surface-mounted and DIN-rail options. The catalog includes single and dual SSRs with AC output, DC input control (typically 4–32 V DC), and integrated fan cooling on select heat sinks. Applications span industrial burner controls, pump motor switching, gas valve actuation, and process heating. Technical buyers can select based on output current, voltage, mounting style, and thermal management requirements. 3G Electric supports procurement with logistics for worldwide shipment, enabling engineers and maintenance managers to source CRYDOM components for new builds or retrofits without geographic restriction.

Frequently asked questions

Common questions about CRYDOM from 3G Electric.

What is the difference between CRYDOM triac and SCR output SSRs?

CRYDOM triac output SSRs, such as the CL240A10C, are suitable for general-purpose AC switching where zero-crossing turn-on is acceptable. SCR output SSRs, like the EL240A10R-05 or C53TP25CH-10, use back-to-back SCRs for higher dv/dt immunity and are often preferred for inductive loads or applications requiring random-turn-on control. Both types are available in the 3G Electric catalog.

How do I select a CRYDOM heat sink for a given SSR?

CRYDOM heat sinks, such as the HS151DR, are rated by thermal resistance (1.5°C/W). To select, calculate the power dissipation of the SSR (output current × voltage drop) and determine the required thermal resistance to keep the junction temperature below the maximum rating. The HS151DR is designed for single or dual SSRs and includes a fan for forced convection. 3G Electric stocks this model for DIN-rail mounting.

Are CRYDOM SSRs with finger-safe enclosures available from 3G Electric?

Yes. Several CRYDOM SSRs in the 3G Electric catalog feature finger-safe enclosures, including the CL240A10C, C53TP25CH-10, and CC2425W3V. These models have touch-safe terminals that meet IP20 requirements, reducing risk during installation and maintenance. Check the product specifications for 'Finger Safe: Yes' to confirm.

What is the input control voltage range for CRYDOM SSRs supplied by 3G Electric?

CRYDOM SSRs in the 3G Electric catalog typically use DC input control. For example, the EL240A10R-05 has an input current of 21 mA, and the CC2425W3V has 10 mA. Most models accept 4–32 V DC input, though specific ranges vary by part number. Refer to the manufacturer datasheet for exact values.

Can CRYDOM dual SSRs be used for three-phase motor control?

CRYDOM dual SSRs, such as the CC2425W3V (25 A) and CD2450W2V (50 A), contain two independent SSR channels in one package. They are commonly used for two-phase switching in three-phase systems, with a third contactor or SSR for the remaining phase. These models are available from 3G Electric with screw-clamp connections.

Does 3G Electric supply CRYDOM products?

Yes — 3G Electric (S) Pte. Ltd. supplies CRYDOM products. We stock the CRYDOM catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
